https://bugs.freedesktop.org/show_bug.cgi?id=45018 --- Comment #88 from Michel Dänzer <michel@xxxxxxxxxxx> 2012-08-03 07:47:17 UTC --- (In reply to comment #86) > So, Anthony has put a finger on something. Yes, I think something like Anthony's patch is needed due to asynchronous GPU processing: when the userspace driver assigns virtual address space for a new BO, the GPU may not have finished processing command streams using previous BOs occupying that same virtual address space. However, the userspace driver shouldn't wait synchronously for the BO to go idle when destroying it but should instead defer destruction (or at least the freeing of the virtual address space) until it notices the BO has become idle. > With Anthony's patch, I'm still able to lock the display everytime And these lockups do not happen when not using virtual address space? Can you provide the dmesg output of the GPU reset for such a lockup? Ideally from a single piglit test reproducing it. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
